3 Claims. (CI. 20-55) This invention relates to storm windows and more particularly to combination storm windows wherein interchangeable screened and/or glazed sash are positioned in a frame which in turn is located on a window opening.

The principal object of the invention is the provision of a simple, light weight, inexpensive combination storm window.

A further object of the invention is the provision of a combination storm window which may be simply assembled from a plurality of extruded metal sections.

A still further object of the invention is the provision of a combination storm window having interchangeable sash located therein and means on the sash for locating and retaining the same in the storm window assembly.

The storm window shown and described herein comprises a main mounting frame formed of cut and mitered sections of three extruded shapes, portions of the mounting frame being modified by application of sections of a fourth extruded shape to provide a frame capable of receiving and retaining a pair of glazed and/or screened sash. The mounting frame comprises a lip type construction engageable on the exterior surface of a window casing and having its top and bottom sections formed to tension the upper and lower edges of the upper and lower sash positioned therein so as to assist in retaining the same in weathertight position therein.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a front plan view of the combination storm window.

Figure 2 is a vertical section taken on line 2--2 of Figure 1.

Figure 3 is a horizontal section taken on line 3-3 of Figure 1.

Figure 4 is an enlarged perspective detail of a portion of one of the side rails of the storm window shown in Figures 1 and 2.

Figure 5 is an enlarged detail of a corner portion of one of the sash shown in Figures 1 and 2 and illustrating the corner key construction.

Figure 6 is a perspective view of the sash corner key shown in Figure 5.

Figure 7 is a bottom elevation of the corner key shown in Figure 6.

By referring to the drawings and Figures 1, 2 and 3 in particular, it will be seen that a combination storm window has been disclosed which comprises a rectangular lip type frame formed of four cut and mitered sections 10, I i, I 2 and I3. The section In comprises a bottom rail and includes a downwardly extending flange it, an upwardly and inwardly extending flange l5 and a T headed flange IS. The T head of the flange l6 has one portion thereof extending outwardly therefrom and including a tapered inner surface I! together with an inwardly projecting ledge l8, it being observed, as best illustrated in Figure 2 of the drawings, that the lower edge of a sash frame l9 will register between the innermost edge of the inturned portion of the flange l5 and the tapered surface ll of the T head of the flange It. This action results in positioning the lower edge of the sash frame I! tightly in the frame section l0.

Each of the frame sections l I and I3 is identical and comprises the side rails and each has an outwardly extending flange 20 and 2|, respectively, the inner surfaces of which are provided with a plurality of axially extending ridges 22 and 23, respectively, which are adapted to be engaged against the window casing on which the storm window is installed. Each of the side rail sections l I and I3 of the mounting frame includes inwardly extending flanges 24 and 25, respectively, and each has a T headed flange 28 and 21, respectively, formed midway thereon as best shown in Figures 3 and 4 of the drawings.

Each of the side rail sections II and I3 of the mounting frame has a modifying section 28 and 29, respectively, positioned therein and secured thereto by suitable fasteners such as rivets 30, it being obvious that metal screws, staples or spot welding may be employed to secure the modifying sections 28 and 29 to the side rail sections II and I3, if desired. It will be observed that'the modifying sections 28 and 29 are identical in cross section and are located in oppositely disposed channels 3| and 32, respectively, in the lower half of the rectangular frame so that the sash frame i9 may be held at its edges, as best shown in Figure 3 of the drawings.

It will be observed that the oppositely disposed channels 31 and 32 are formed between portions of the modifying sections 28 and 29 and that angular extensions 33 and 34 formed on the modiare cut away adjacent the uppermost ends thereof to form a lowered step-like portion, the upper end of which is indicated by the numeral 36 and which cut away section shortens the efliective length of each of the innermost flanges 31 and 38 of the modifying sections so that the channels 3| and 32 formed therein are in effect shortened to permit the sash frame l9 to be-positioned therein for registry therewith and so that it can be removed therefrom.

The top section I! of the mounting frame comprises an extruded shape having a downwardly extending flange 39 and an upwardly extending flange 40.- The back or inner face of the upwardly extending flange 40 is provided with a plurality of longitudinally extending ridges 4| as best shown in Figure 2 of the drawings, and is adapted to register with the top portion of the window frame on which the storm window is installed. The section l2 comprises the top rail of the mounting frame and is provided with a T- headed inwardly extending flange 42 comparable in all respects with the T headed flanges 21 formed on the side rails II and i3. The T headed flange 42 has a downwardly extending secondary flange 43 positioned thereon, a port on of which is bowed in the direction of the flange 39 so that a relatively narrow inverted channel 44 is formed between the flanges 43 and 39 and which is adapted to receive the uppermost edge of the upper sash frame 35.

It will be observed by referring to Figure 2 of the drawings, that the vertical height between the upper ends of the modifying sections 28 and 29 and the inner surface of the T headed flange is greater than that of the over-all height of the upper sash frame 35. This clearance provides for additional means to secure the upper sash frame 35 in position in the storm w ndow frame. The additional means comprises the formation of the lower pair of sash corner keys 45 with downwardly projecting lugs 46 which are adapted to register in the open portions of the modifying sections 23 and 29, respectively and thereby hold the lower edge of the upper sash frame 35 against movement. Similar sash corner keys 4! are used on the uppermost corners of the sash frame 35 except that the lugs 46 heretofore referred to are omitted. The sash comer keys 4! are also employed in the formation of the sash l9 heretofore referred to. n Figures 6 and '7 of the drawings, detailed illus rations of the sash corner keys 45 are disclosed.

In Figure of the drawings, a corner section of the sash 35 is shown with the corner key 45 in position therein and the lug 46 projecting therebelow. The keys 45 are secured in channels formed in the outer edges of the sash frame 35 and the material of the sash frame is distorted as by a crimping operation to forcibly engage the sash corner keys 45 and thereby form an effective sash frame which is adapted to receive and retain a pane of glazing material 43 as by means of splines 49 formed of spring-like material.

The four sections III, II, I2 and ll of the mounting frame of the storm window are. cut and mitered at their ends and secured to one another by the use of L shaped frame corner keys 50, as best shown in Figure 2 of the drawings, it being observed that the frame corner keys lie beside the T headed flanges I3, 21 and 42, respectively. They are retained in position by crimping the T head of the flanges I3, 21 and 42 into depressions formed in the sides of the frame corner keys 50. Axially extending ribs II are formed on each of the sections Ill, ll, l2 and I3, spaced with respect to the T headed flanges I4, 23, 21 and 42, respectively, to provide means locating the transversely flat frame comer keys II In operating the storm window, it will be observed that the lower sash frame I! may be raised from the position shown in Figures 1 and 2, forexample, until the lowermost edge thereof lies above the top end 33 of the cut away section of the modifying sections 23 and 29. The sash frame l9 may then be moved outwardly, to 'the right in Figure 2, of the storm window assembly and a similarly formed screened sash substituted therefor. When the upper sash frame 35 is to be removed, it is elevated slightly to clear the lugs 46 from their normal registry in the upper open ends of the modifying sections 23 and 29 and it is then swung outwardly of the storm window assembly after first having its upper edge disengaged from the channel 44 heretofore disclosed. It will thus be seen that in normal closed position, the sash frames l9 and 35 are in the position shown in Figures 1 and 2 of the drawings and that their meeting rails lie adjacent one another on the same horizontal plane with the sash frames themselves positioned in double hung relation.

It will further be observed that in such normal closed position, the lower sash frame I! is wedged into the section it! so that a mechanically tight joint is formed between the edge of the inturned portion of the flange l5 and the sash frame ll while the upper edge of the upper sash frame 34 is tightly held in the restricted channel 44 as heretofore described. Any water entering the window assembly will be drained therefrom by punched openings formed in the T headed flange IS on the frame section l0.

It will thus be seen that a simple and emcient combination storm window has been disclosed which possesses several advantages in construction, simplicity of metal sections from which it is formed and ease of assembly with an interdependency of operation between the sash and the frame in that the sash carry some of the means for retaining their predetermined position in the frame.

Having thus described my invention, what I claim is:
